SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 415,103, dated November 12, 1889.

Application filed April 27, 1889- I To all whom, it may concern.

Be it known that I, ELDRIDGE J UDSON Gonat Anagance, in the county of Kings, New Brunswick, Canada, have invented anew and useful- Snow-Plow, of which the following is a specification.

My invention relates to improvements in features hereinafter described and claimed. In the accompanying drawings, Figure 1 is a perspective view. Fig. 2 is a plan view. Fig. 3 is a central vertical longitudinal section; Fig. 4 is a transverse vertical section looking toward the front. Fig. 5 is a detail perspective View of the rotary knives. Fig. 6 is an enlarged side View of the wheelscrapers and the levers for operating the same.

- In carrying out my invention I employ, the longitudinal beams A A, in .which the axles B B, carrying the supporting-wheels O C, are journaled, and these beams are connected at their front and rear ends by the cross-bars D D, as shown. Upon the upper side of the rear cross-bar D, I secure a transverse end plate E, in which the coupling F is mounted, so that the plow can be coupled to the front snow.

To the front ends of the beams A A, I secure the forwardly-projecting scraper G, the upper surface of which is inclined upward and rearward, and is divided into a series of longitudinal troughs H, separated by vertiso that the snow will be thoroughly cut up and broken as the machine is pushed forward. The floor J extends rearward from the scraper G on an upward incline, so that as the machine is pushed forward a wedging action will be exerted on the bank of snow from the bottom of the same, so as to lift it and divide it, as will be readily understood. Beneath the floor J, at the side edges of the same, I secure the depending vertical plates K, which extend outside the wheels, so as to protect them from the snow and prevent the snow working under the machine, so as to throw it from the track.

On the upperside of the floor J, I arrange the deflecting-plates L L, which have their,

snow to one side as it is broken up by the machine and moves up the inclined floor of the same. 011 the sides of the machine, adjacent to the ends of these deflecting-plates,

I arrange the wings M, which are pivotally secured to the frame, and are operated so as l to be turned inward or outward by a double crank N on a vertical rock-shaft O, mounted in the floor near the rear end of the same and provided with a hand wheel P at its upper end, so that it may be operated through suitable chains from the locomotive, the wings being connected to the said double crank by the pitmen N.

On the upper side of the floor J, at the side edges of the same and near the front end thereof, I erect the wallsQ,which are secured to suitable supporting-standards R and braced by the cross-beams S, as shown. Between the front ends of these walls Q, I secure a series of rigid horizontal knives T,which are adapted to enter the snow-bank and cut and break up the snow, and these knives are braced by a standard U, erected on the scraper at the center of the same, as clearly shown. In rear of these stationary knives T, and adjacent to the front ends of the deflecting-plates L, I mount a rock-shaft V, having a hand-wheel W at its upper end, to which suitable chains are secured and extended back to the locomotive. On this rock-shaft V, I secure the forwardly-projecting vertical cut-off plate X, which is adapted to be turned to one side or theother to throw the snow to one or the other side, as will be readily understood. If the machine is being used on a single track this ary vertical knives .Y, I. arrange a horizontal rotary shaft Z, which is journaled in the walls Q and the deflecting-plates L, and is provided at its center with a grooved pulley or disk a, connected by a belt I) with a similar pulley c on the rear axle, as shown. This shaft Z is provided with a number of radial knives (Z, and as the machine is pushed forward will be rotated through the belts and pulleys described, so that the said radia'l knives will be forced to thoroughly agitate the snow and break it up into small particles.

To the inner sides of the beams A A, I pivot the lovers 6, which are connected at their rear ends by the cross-bars f, and have the scrapers g depending from their front ends and adapted to act 011 the front wheels. In rear of these levers e, I pivot to the beams A the similar levers h, which have the scrapers 11 depending from their rear ends and adapted to act on the rear wheels, and the front ends of the levers h are pivoted to the ley'ers 6 between the pivot of the same and the rear end thereof, so as to secure a simultaneous operation thereof. These levers are ing bar j, connected at its lower end to the cross-bar f and extending upward through the rear end of the machine, and a hand-lever 7r,

pivoted atone end upon the frame and at an intermediate point to the upper end of the bar j.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the operation of my improved snow-plow will be readily understood. The plow is coupled in front of a locomotive and is pushed forward therebyinto the snowbank, so as to break up the snow and throw it to the side of the track, leaving the track free for the passage of the train. The scraper G at the front end of the machine has its front edge about on a level with the top edges of the rails, so that the said scraper will enter the snow-bank near the ground and consequently lift the same, so as to loosen and separate the particles of snow. As the machine is pushed forward the stationary horizontal knives, the stationary vertical knives, and the rotary knives act successively on the snow, so as to thoroughly break up and separate the particles thereof. At the same time the snow will be forced up the inclined floor of the machine and thrown to one side by the deflecting-plate, as will be readily understood, and in order that the snow may not fall back in rear of the plow the wings M are thrown out, so as to push the snow away from the sides of the plow.

It will be seen from the foregoing that I have provided a very strong and durable snow-plow by the use of which large snowdrifts can be readily broken up and removed from the track without great 'strain being thrown on the locomotive, and its advantages are thought to be obvious. The axle may be provided with a loose drum, so that when there is no necessity for the rotary knives operating, the beltcan be shifted onto this loose drum, as will be readily understood.

Having thus deseribed'my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a snow-plow, the combination of the scraper provided in its upper side, at its front end, with a series ofinclined longitudinal troughs H, separated by the vertical partitions I, having sharpened frontends, the vertical walls Q at the side edges of the scraper, and the horizontal stationary knives secured to the side walls Q and extending between 1 the same above and out of contact with the partitions I, as set forth. operated by means of a vertically-reciprocat 2. In a snow-plow, the combination, with the frame, of the wings pivotally mounted on the sides of the same, the vertical rock-shaft arranged between the wings, the double crank 011 said shaft, and the pitmen connecting said crank with the wings, as set forth.

3. A snow-plow having the horizontal stationary knives T at its front end and having stationary vertical knives Y arranged in rear of the said horizontal knives, as set forth.

4. A snow-plow having the horizontal knives T, the vertical knives Y in rear of the horizontal knives, and rotary knives arranged in rear of the vertical knives, as set forth.

5. The combination, with the beams A, of the levers pivoted thereon and having scrapers at their ends adapted to act on the wheels, as set forth.

6. The combination, with the beams A, of the levers e, pivoted thereon, the scrapers depending from said levers and adapted to act on the front wheels, the levers h, pivoted thereto and also to the levers e, the scrapers depending from said levers and adapted to act on the rear wheels, the cross-bar connecting the ends of the lever e, the bar connected to the cross-bar f, and the hand-lever 75, adapted to depress said bar, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
